Title: Improvements in or relating to automatic ordnance
IPC: F41A9/16
Filed: 1943-12-20
Abstract: 808,479. Setting projectile fuses; loading ordnance. HARVEY V. P. H., PARRY, F., and MOLINS MACHINE CO. Ltd. Jan. 20, 1945 [Dec. 20, 1943], No. 21372/43. Drawings to Specification. Classes 9(1) and 92 A fuse-setter is mounted on the transversely-swinging loading-tray of an automatic gun (e.g. a 5.25 inch anti-aircraft gun) so as to be capable of (a) longitudinal displacement on the tray to engage the projectile fuse, (b) rotation of the setter proper to set the fuse, (c) displacement away from the fuse, and (d) lateral displacement to enable the tray and projectile to continue their movement to the loading position, in which the projectile is presented 'for loading by an automatically-operated rammer, as described in Specification 578,621, followed by automatic firing of the gun and return of the tray and fuze-setter to the receiving position. The longitudinal displacements are effected by a lever mechanism, including an extensible spring link to allow for rounds of different lengths, actuated by a cam on the gun cradle. The rotation of the setter is effected by a train of pinions, including a lost-motion device, driven either by an arcuate rack on the cradle or by a separate motor. The setter is uncoupled from the tray, after the fuze has been set, by the release of a pawl by a cam on the cradle. Provision is made in the gear train for a continuous adjustment of the setter for the changing conditions of the target. Means are provided in the gun cradle to prevent rounds being fed to the loading tray except when the latter is in the receiving position. As the tray reaches the latter postion, it may energize a solenoid which operates through levers, the firing mechanism of the gun.

Title: Improvements in and relating to timing devices for electric circuits
IPC: H01H50/88
Filed: 1939-07-27
Abstract: 531,585. Escapements. BRITISH THOMSONHOUSTON CO., Ltd. July 27, 1939, No. 21810. Convention date, July 28, 1938. [Class 139] [Also in Group XXXVII] A timing device particularly for delaying the starting of meters comprises a balanced oscillating weight 49 pivoted at a pin 50 fixed to a frame 22 and an escapement member 46 pivoted on a pin 47 fixed to the frame and having secured to it an arm 51 which is pivoted on an extension of the pin 47 both arm 51 and weight 49 being slotted and connected to an adjusting screw 54, the member 46 engaging a scape wheel 45 connected to its shaft by a one-way ratchet clutch.

Patent GB-769450-A (GB)
Title: Improvements in or relating to the mass analysis of ions
IPC: H01J49/02
Filed: 1954-07-27
Abstract: 769,450. Mass spectrometers. HIPPLE, J. A. July 27, 1954 [Aug. 3, 1953], No. 21883/54. Class 39(1). Ions of a specific mass-to-charge ratio are selected from a gaseous mixture by (a) ionizing the mixture, (b) applying to the resulting ions impulses which give them energies which are inversely proportional to the mass-to-charge ratio, and (c) collecting ions having energy equal to or greater than that of the selected ions and repelling the others. For high resolution these operations must be carried out periodically so that no ions are generated during the impulse (b). As shown, ions are generated in chamber 4 by a pulsed electron beam (shown dotted) from cathode 8. The beam is then switched off and an impulse is applied to side electrode 5. If the impulse is such that it is over before any ions reach perforated side wall 6 the different ions will all receive equal momenta and thus satisfy condition (b). By adjusting the potential of collector 7 the selected ions can be segregated from those having less energy. It is stated that segregation can still be obtained when some of the lighter ions reach the wall 6 before the impulse is over, or when some of the heavier ions dwell in the chamber 4 for more than one impulse. Electrostatic deflecting means may be used for energy separation and magnets may be used for collimating the beam. A closer selection of the desired ion may be obtained by modulating collector electrode 7 at, say, 100 cycles per second over a range of potential in which the desired ion is successively collected and repelled ; the alternating component of the collector current is proportional to the desired ion current. Grids may be used to screen collector 7 from the rest of the apparatus.

Title: Improvements in or relating to apparatus for electrolytically depositing chromium
IPC: C25D17/06
Filed: 1928-07-28
Abstract: 320,440. Soc. Chimique de la Seine, and Szidon, V. July 28, 1928. Electrodes, moving; supporting; connections; chromium, depositing.-Articles 10, Fig. 1, to be chromium-plated are supported on a copper bar 6 fitting within insulating supports 7 at the top of racks 8.

Patent GB-1016421-A (GB)
Title: Weighing apparatus
IPC: G01G3/13
Filed: 1962-06-06
Abstract: 1,016,421. Electric signalling. CARL SCHENCK MASCHINENFABRIK G.m.b.H. June 6, 1962 [June 29, 1961], No. 21947/62. Heading G4H. [Also in Division G1] An automatic weighing machine comprises a balancing mechanism, an adjustable counterbalancing means, means for generating two frequencies dependent upon the momentary differential force between a load and the counterbalancing means, means for converting the frequencies into pulse trains, means for comparing the pulse trains for the purpose of generating difference pulses and means responsive to the difference pulses for determining the state of balance between the load and the counterbalancing means. A load applied at 3 is automatically counterbalanced by weight 4, and crystals 15, 16 are stressed as a result. The crystals are connected to oscillators and under zero load at 3 oscillate at the same frequency. Their outputs are applied to pulse generators 22, 23 which are connected to subtracting elements 24, 25. These elements are interconnected and supply a pulse to storage elements 26, 27 only when a pulse applied to one of the elements 24, 25 is not cancelled by a pulse to the other. Elements 26, 27 clear each other, or may be cleared by a pulse from a selector switch 30, selection depending upon the direction of rotation of a motor 29. As long as a pulse is stored in one of the elements 26, 27 motor 29 is energized through switch 32. The motor operates a pulse generator 28, comprising a toothed wheel 33 and optical detectors illuminated or obscured by areas 34, 35 (Fig. 2). A pulse is generated only when the motor has rotated through about one toothpitch, thus eliminating oscillatory effects. Selection by switch 30 then depends on the illumination sequence of the detectors. The motor drives a sliding counterweight, or operates a weight depositing or removing mechanism, or controls the load. When motor 29 is to be stopped switch 32 may simultaneously provide a braking voltage. In a modification the pulses indicative of the difference between the frequencies of the pulse trains, or between the pulse lengths, from generators 22, 23 are converted to a direct voltage indicative of the magnitude and sense of the difference, which voltage may be used directly for control, or may be compared with a voltage from a tachogenerator coupled to the servomotor shaft, and the difference used to drive the motor via an indicator. Other strain sensitive generators such as tensioned steel wires, membranes, or tuning forks may replace crystals 15, 16. Specification 1,016,422, which is divided from this Specification, is referred to.
